Linked Lists using structs embedded in classes

• v1: These files show a start at implementing an "Account" object as Acct_C. However this set of files doesn't compile. There are two problems in the main. What are they?
• v2: This version fixes the problems in v1. The next step is to write an implementation file for the Acct_C class, which is tacked in v4.
• v3: This version fixes the problems in v1 in a different way. Here, instead of an array of Acct_C objects, we have an array of Acct_C pointers. The objects are not created until after the name and account number are known. This is in some ways a better solution... why?

  Note that we had to change the . operator to a -> operator.

• v4: Now we tackle the .cc file for the Acct_C class. Our first attempt doesn't work. What is wrong?
• v5: This fixes the problem encountered in v4.
• v6: Now we are ready to add a Makefile
• v7: Finally, we will add a class which encapsulates the idea of a "list of accounts". Our first version will stay with an implementation that uses an array. Then we'll show how the same "interface" (i.e. public member functions) can be used to implement the list as a class.
• v8: This version has the same public interface as v7; that is, we have the same main, and the same public class members. However, the private part, and the implementation of the members are different; here we use a linked list instead of an array. This version has a logic error in the code that adds to the linked list. Observe the output, and indicate what the error is.
• v9: In this version the error is fixed. You can use the "diff" command as in:

  diff v8/acctList.cc v9/acctList.cc

  to see the differences and to see what was fixed.
